Abstract
The utility model relates to a range upon range of formula transformer, including primary outlet, primary winding, secondary lead -out wire, secondary, insulating part, iron core, its characterized in that primary winding is connected with the primary outlet, and secondary is connected with secondary lead -out wire, and secondary sets up in the primary winding top, is provided with the insulating part between secondary and the primary winding, and outside secondary's lower plywood was located to the insulating part cover, the iron core cover was located outside the range upon range of primary winding and secondary. The utility model discloses an overlap primary winding and secondary to be provided with the insulating part between secondary and primary winding, increased the insulating nature between primary winding and the secondary. Adopt range upon range of formula transformer owing to adopt the design of range upon range of formula, have the characteristics that coupling nature is good, small, outside range upon range of primary winding and secondary were located to the iron core cover moreover, in the transformer use, the skeleton was difficult for expansion deformation, can reduce the interior vortex of iron and [magnetic] hysteresis loss.
Description
Technical field
The utility model relates to electrical equipment, specifically laminated type transformer.
Background technology
Transformer (Transformer) utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: power transformer and special transformer (electric furnace change, rectification change, power frequency testing transformer, voltage regulator, mining change, audio frequency transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, instrument transformer etc.).
Transformer is generally made up of iron core (or magnetic core) and coil, and coil has two or more winding, and wherein connect the winding of power supply primary coil, remaining winding is secondary coil.Effect unshakable in one's determination is the magnetic coupling between reinforcement two coils.In order to reduce eddy current and magnetic hysteresis loss in iron, iron core is formed by the silicon steel plate stacking of painting; Do not have the contact of electricity between two coils, coil is coiled into by insulated copper wire (or aluminum steel).A coil connects AC power and is called primary coil (or primary coil), and another coil connects electrical appliance and is called secondary coil (or secondary coil).At present transformer ubiquity coupling difference on the market and the shortcoming such as volume is large, in prior art, armature winding, secondary winding wound are on same skeleton, iron core (two sections of merging) is sheathed on outside skeleton, in transformer use procedure, skeleton is heated easy dilatancy, and the iron core being sheathed on its outside, because of framework deformation, causes it to connect deleterious, the magnetic coupling between two coils can be reduced, increase eddy current and magnetic hysteresis loss in iron simultaneously.
Summary of the invention
The utility model, just for above technical problem, provides that a kind of coupling is good, volume is little, and iron core sleeve is located at the laminated type transformer outside stacked armature winding, secondary winding.
The utility model is achieved through the following technical solutions:
Laminated type transformer, comprise primary outlet, armature winding, secondary lead-out wire, secondary winding, insulating part, iron core, it is characterized in that armature winding is connected with primary outlet, secondary winding is connected with secondary lead-out wire, secondary winding is arranged on above armature winding, be provided with insulating part between secondary winding and armature winding, insulating part is sheathed on outside the lower plywood of secondary winding, and iron core sleeve is located at outside stacked armature winding and secondary winding.Insulating part entirety is half shaped as frame.Insulating part cross section is half shaped as frame.Primary outlet, secondary lead-out wire are that spininess pin is drawn.Armature winding, secondary winding entirety are rectangular.
The utility model by carrying out overlapping by armature winding with secondary winding, and is provided with insulating part between secondary winding and armature winding, adds the insulating properties between armature winding and secondary winding.Adopt laminated type transformer described in the utility model owing to adopting stacked design, have the advantages that coupling is good, volume is little, and iron core sleeve is located at outside stacked armature winding and secondary winding, in transformer use procedure, skeleton is dilatancy not easily, can reduce eddy current and magnetic hysteresis loss in iron.
The utility model structure is simple, with low cost, easy to use.
